nitrile rubber
Nitrile Rubber Sourcing is an independent procurement desk for US buyers of nitrile rubber. We do not vulcanize compound, hold a warehouse, or publish a price list. Share the form, Shore A or Shore D hardness, quantity and destination so several factories can quote the same nitrile rubber line.
Which purchasing requirements separate nitrile rubber from neighbouring options
The home term is nitrile rubber. Neighbouring strings on this site — nitrile rubber gloves, nitrile rubber sheet, nitrile rubber gasket, nitrile rubber o ring cord — are request languages, not five stocked SKUs. A factory that fills those gaps itself will not quote the same line as a factory that waits for the axes below.
Molding compound
Acrylonitrile content band, cure system, tensile strength in MPa or psi, and the lot document that belongs to the quoted pellet or slab.
Align a requestHardness band
Softer and harder inquiry options still need one durometer scale. Shore A and Shore D are not interchangeable on the same line.
Check a quoted scaleColor-matched lots
Color-matched Nitrile Rubber is a request for a named color or sample, not a claim that this desk holds pigment inventory.
Send a color briefWhat a complete nitrile rubber request has to contain
The buyer still decides the form, hardness scale, density and destination. This desk does not fill those fields from a catalogue default. The table compares two reviewed inquiry forms so two factory replies can be read on the same axes.
| Axis the buyer still owns | Nitrile Rubber sheet stock inquiry option | Nitrile Rubber molding compound inquiry option |
|---|---|---|
| Shore A or Shore D hardness | Name the scale and value on the sheet line | Name the scale on the compound; do not mix A and D |
| Density | g/cc only if used to distinguish grade | g/cc or specific gravity on the quoted lot |
| Service temperature | °F or °C with the medium (oil, fuel, air) | °F or °C for the intended molding service |
| Grade and ASTM | Grade designation and ASTM D2000 callout if required | Grade designation and the method the lot was tested under |
| Form and packing | Sheets on a pallet; thickness + L × W | Bag, box or gaylord; net kg |
How this desk reads a nitrile rubber brief
-
1. Name the form first
Sheet stock, molding compound, softer, harder or color-matched. Gloves, sheet, gasket and o-ring cord language belongs on the request only when that is the construction being bought.
-
2. Keep Shore A and Shore D apart
A 70 Shore A gasket line is not a Shore D number. Two prices mean the same thing only after every offer states the same scale.
-
3. Ask for the document on the quoted item
A plant ISO 9001 file is not a lot tensile, elongation or compression set page. REACH or RoHS statements, if required, must name the quoted grade.
-
4. Compare total procurement cost
Packing, Incoterms, sample split and documents sit next to the money figure. This desk does not recast a unit number as a market-beating percentage.
Files to request from the named supplier
Certificates belong to a factory and a quoted configuration. They are not Nitrile Rubber Sourcing badges.
-
ASTM D2000 / grade designation
Ask which published figure and which standard were used to state the grade. A brochure family name is not a callout.
-
Hardness and compression set
Shore A or Shore D plus compression set % under the named ASTM D395 condition if sealing force matters.
-
Food-contact or automotive files
FDA 21 CFR 177, NSF 51/61 or IATF 16949 evidence only when the buyer asked for them, and only on the quoted grade and lot.
-
REACH / RoHS / Prop 65 statements
Company-level letters do not replace a statement that names the quoted nitrile rubber line.

Procurement situations, not customer testimonials
These are check examples. They are not named reviews, savings claims or factory endorsements.
A buyer sent “nitrile rubber” and two factories answered with glove boxes. The request had to name sheet thickness and Shore A before the third reply could be compared.
One offer listed 70 hardness with no scale. The other listed 70 Shore A and a density in g/cc. Only the second line could sit next to a drawing.
A plant certificate arrived without a lot tensile or ASTM D2000 callout. The desk sent it back; a company file is not the quoted item.
Send a nitrile rubber brief
Write the form, Shore A or Shore D hardness, density in g/cc if used, quantity, destination and the documents you need. We will ask more than one factory to answer that same list.
